A media drive is disclosed. In one embodiment, a media drive can comprise: a disk holder, a drive laser, a disk reader, and a luminescence detector. The disk holder can be capable of applying a rotational force to a media disk. The drive laser is disposed so that light from the laser will be incident on the media disk when it is disposed in the disk holder. The disk reader is disposed to receive data from the media disk. A method for authenticating a media disk is also disclosed. The method can comprises: disposing the article in a reader, illuminating at least a portion of the article with the information reader, monitoring a luminescence emission of the illuminated article, and determining if the luminescence emission is consistent with an authentic article. If a luminescent material is present, the information reader excites the luminescent material to create a luminescence emission.

An apparatus includes an article and a detector. The article includes a substrate, a faceted structure disposed on the substrate, and a sensor layer disposed on the faceted structure. The faceted structure is disposed on the substrate first surface and itself has a surface. The faceted structure surface has peripheral edge defining a diameter of the faceted structure surface. The sensor layer is disposed on the faceted structure surface. The sensor layer can react or can interact with a target species when the target species is sufficiently proximate to the sensor layer. The sensor layer responds to the reaction or to the interaction in a detectable manner. The detector detects a response to the reaction, or to the interaction, of the target species with the sensor layer.

An apparatus for monitoring the performance of a distributed system is provided. The distributed system comprises a plurality of cooperating units disposed in a communications network. The apparatus comprises a plurality of diagnostic components wherein each unit of the system comprises at least one of the diagnostic components. Each diagnostic component comprises a sensor, a data reduction module, a transceiver and a data analysis module. The sensors sense unit performance characteristics and represent the characteristics as raw data. The data reduction module receives and processes the raw data produced by the sensors to generate reduced data. The transceiver receives the reduced data from the data reduction module and transmits and receives the reduced data to and from the units using the network. The data analysis module accepts and analyzes the reduced data from the transceiver to produce performance data related to the distributed system.
